Ferrari driver Fernando Alonso has expressed his sadness at the news that Felipe Massa will be ending an eight-year spell with the Italian team at the end of this year's World Championship.
Massa will be looking for a new race seat in Formula 1 after Ferrari confirmed that former driver Kimi Raikkonen is make a stunning return to replace the driver for 2014.
Alonso has been the team-mate of Massa since joining the team in 2010, when ironically he replaced the returning Raikkonen, and he took to his Twitter page to pay tribute.
He said: "I want to thank Felipe for all the support he has given to me and the team during this journey we have made together over all these years.
"Come the end of the season, it will not be easy to say goodbye to a team-mate like him.
"He has always been truly professional and loyal to the team and I am sure that right to the end, he will do his utmost for the Scuderia that he loves so much."
He also made a more personal message to Massa, accompanied with pictures of the pair during their years racing together.
It read: "All the luck for the next few years.
"You will be a strong opponent in any team and we still have seven Grand Prix to have some fun."
Alonso is rumoured to have been unhappy about the appointment of Lotus driver Raikkonen, and did not mention the Finn's name, instead just choosing to welcome his "new travelling companion".
The 32 year-old is believed to have wanted a partner who can play the number two role to him as Massa did, and knows he will be battling Raikkonen for the top positions next year.
In 2008 Massa was just a single point away from winning the Drivers' World Championship with Ferrari.
However the Brazilian suffered a horrific injury in qualifying for the 2009 Hungarian Grand Prix, and, after a lengthy lay-off from the sport, never managed to finish higher than sixth.
Massa is linked with taking the seat vacated by Raikkonen at Lotus next year, however he faces competition from Sauber's Nico Hulkenburg.
